SELF-CLOSING AND siPHoN VALVE.

SPECIFICATION forming part of Letters Patent No. 272,668, dated October 18, 1904.

- Application filed Jane -23,1902. sari-n in. 90,912. (Nb model.)

To all whom it may concern.-

Be it known that I, ARTHUR OBRIEN, acitizen of the United States, and a resident of the city of Chicago, in the county of Cookand State of Illinois, have invented certain new anduseful Improvements in Self-Closing and Siphon Valves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. I

This invention relates to improvements in valves of that class embodied in my application for patent on faucets, filed September 9, 1901-, Serial No. 7 4, 7 7 5, in which the faucet-body is provided with a central bore and an internal cylinder forming an annular cup between said cylinder and the body and providing a valveseat against which the plunger-valve engages.

The invention is shown more. particularly as embodied in a faucet designed to be selfclosing against any desired pressure.

The object of the invention is to provide a valve for faucets or other purposes, so con-- structed as to avoid'neces'sity of using packing of any kind, and also to provide self-contained means acting to close the valve automatically against any desired pressure.

It is a further object to provide means for v adjusting the valve to different pressures.

The invention consists .of the matters hereinafter described, and more fully pointed out and defined in the appended claims.

In the drawings, Figure l is a vertical longitudinal section of valve embodying myinvention. Fig. 2 is'a front elevation of the valve-closure and deflector-hood, Fig. 3 is a section taken on line 3 '3, Fig. 2. Fig. 4 is a detail of a modified form of the eccentric and cam-seat. which'cooperate'to lift the valve.

Fig. 5 is a section taken in line 5 5 ofFig. 1.

As shown. in the drawings, A indicates a fauce tbody of the usual or any desired type, as

shown,.however, having a downwardly-turned nozzlebr' spout a, .and provided onits top with the upwardlyr'extending integral sleeve A designed'to contain part of theoperating means for the valve. Within the faucet-body and in a line with-the rear side of the sleeve A are the downwardly-extending wall a, integral with a horizontal apertured partition a and a-downwardly-extending partition a integral with the front side of partition a which together divide the faucet-body into two chambers A and A, which communicate only through the aperture in the horizontal portion (0 Connected integrally on the upper side of said partition of and registering with the aperture therein is the relatively short upwardly-extending sleeve A into sleeve AL Within the casing A is a vertical movable valve-closure B, adapted to fit closely on the upper end of the sleeve A and, if preferred, providedwith a washer, of indurated fiber, rubber, or other material, adapted to be readily renewable and to afford a close fit on the end ofsaid sleeve. The width of said closure is slightly greater than the outer diameter of the sleeve, and a downwardly-directed peripheral flanget is integrally secured thereon and apertured on the front side or that opening into the chamberAf or to the spout, as shown inFigs. 1, 2, and 3. Said opening is preferably so shaped as to. converge the flow into the delivery-orifice. Said flange t forms a hood about the sleeve A acting to deflect the fluid downwardly as it lflows'fr'om the sleeve A Connected centrally on the valve-closure B is the valve-stem, which extends upwardly in the sleeve A. Said-stem intermediate of its ends fits closely in said sleeve, as indicated at 6 but is greatly reduced in diameter at 6,

adjacent to the closure B, providing an annular vacuum-chamber immediately above the closure, which-opens toward the spout and which is limited above by the horizontally-extending surface of the stem which serves as a deflector. Said stem is also reduced in diameter near its upper end to providean annular upwardly-directed shoulder to receive the spring C, which engages against said shoulder and againstan adjustable nut D, having screw threaded engagement in the top of a cap E, which, asshown, is removably secured on said sleeve A, as shown, having screw-threaded engagement therewith.

Means are provided for rotating said nut D,

comprising a nipple D, provided with astem (Z, which extends through the cap E into positive engagement with said nut and by the rotation of which said nut may be moved up or down in said cap, thereby regulating the pressure on the valve-closure, as desired.

Means are provided for actuating the valve comprising the double downwardly-projecting cam F, rigidly secured on a shaft f, journaled at its ends on opposite sides of the sleeve A. Said shaft extends centrally through the stem, which is vertically slotted to receive the same and to permit vertical movement of the stem. Communicating with said aperture is a forwardly-opening recess in the stem, having divergent curved upper and lower walls, within which fits the cam F. Said cam is so formed as to positively engage both walls of the aperture in any of its 'adjusted positions, which prevent movementindependent of the cam and provides a maximum lift for the valverclosure with slight movement of the lever attached at one end of the shaft, this insuring a maximum flow of fluid through the orifice of the valve. When in its elevated position, the stem sustains the strain of the spring, and the support by the cam is unstable, so that when the lever is released the valve-closure is forced downwardly against the flu id-pressure, sh uttingoff the flow.

The operation is as follows: The valve when adjusted to withstand a desired pressure will manifestly remain closed against such pressure until lifted by the cam. IV hen the valve is lifted, the water or other fluid flows upwardly through the sleeve A outwardly through the opening in the front side of the deflecting-hood b, and owing in part to the shape of said orifice in a copious stream from the faucet. If opened to its fullest capacity, the chamber A will be nearly filled with the outwardly-flowing fluid, which by the deflecting-hoodb is directed downwardly. Said outflowing current of fluid operates to carry with it a portion of the air originally contained in the annular chamber surrounding the stem portion 6, quickly forming a partial vacuum above the valve-orifice and producing a positive inflow of air through the sleeve A, the portion of the sleeve extending above said annular chamber being never wetted by the flowing fluid.

Obviously valves constructed as indicated may be used for many different purposes and constructed in many different forms, the same being as useful for controlling the flow of' any kind of fluid in any condition. Obviously also said valve is adaptable for all uses in which a valve destitute of packing and self-closing may be desirable. Obviously it is not essential that a cam or an eccentric be employed for lifting the valve-closure inasmuch as the same may be accomplished by many other means, and it is my purpose to illustrate but one of many uses for valves embodying theinvention and one of many means for operating said valves.

Obviously many details of the invention maybe varied without departing from my invention.

I claim as my invention 1. A valve comprising in combination with the valve-seat, a valve-closure and an apertured part adjacent to the valve-closure and fitting closely about the valve-seat adapted to converge the stream of fluid as it passes through the valve.

2. In a valve the combination with a valveseat of a valve-closure, a depending peripheral flange thereon, adapted to lit closely around said seat and provided with an aperture in the front wall thereof for the escape of fluid therethrough.

3. In a valve the combination with a valve seat of a closure therefor, a cup-shaped deflector tightly inclosing said valve-seat, and provided with an aperture in the front wall thereof and an air-chamber above said closure.

4. In a valve having an unrestricted delivery-nozzle, the combination with a horizontally-apertured partition therein, a sleeve extending upwardly from said aperture and forming a valve-seat, a valve-closure therefor, an aperture-d efleetor integral with the closure and closely engaging said seat and an airehamber above said closure wherein a partial vacuum is created by the fluid directed into the nozzle by the deflector.

5. In a valve having an unobstructed delivery-orifice, the combination with a val ve-seat, of a valve-closure therefor, means integral with the margin of the valve-closure adapted to divert a part of the fluid moving through the valve from its normal course, an air-chamber above the closure and a supplemental deflector forming the top of the air-clnunber, said deflectorsacting to direct all fluid passing through the valveinto the delivery-orifice whereby when the valve is opened the moving current acts to exhaust the air in the chamber.

6. The combination with a valve-casing, of a partition dividing the same into an inner and an outer chamber and having therein a valve-seat, a valve-closure seated therein, means carried thereon for diverting the current directed through the valve from the upper chamber to the point of delivery, and means operative within the casing for adjusting the valve to a desired pressure.

7. The combination with a two-chambered val ve-casing havingan unobstructed deliveryorifice, of a sleeve through which the chambers communicate, a valve-seat thereon, a valve-closure therefor, a deflector carried on the valve-closure and extending around said sleeve, a deflecting-guide above the valve-closure and adjustable upon the casing, a nut in screw-threaded engagement with the inner surface of said cap, resilient means engaging beneath the nut and acting to force the valve closure into positive engagement on the valve-v seat and means for lifting the valve-closure.

8. In a valve of the class described the combination with the valve-casing, the valve-closure and Valve-stem of a cam pivoted centrally of said stem and engaging in a recess in the stem and acting to lift the valve-closure, said cam and its recess being so formed as to provide a plurality of points of contact at all times.

9. The combination with avalve-casing divided into an inner and outer chamber by an apertured partition, of a valve closure, a sleeve surrounding the valve-closure and provided adjacent to the point of delivery of the valve with an opening therethrough, having a downwardly-inclined top Wall, a deflectingguid'e carried on the valve-stem above the upper end of the sleeve, an adjustable cap on the valve-casing, a springengagingin the cap acting to hold the closure seated and means scribed my name in the presence of twosubscribing Witnesses.
